There are two major couples expressing their feelings for each other. And besides that, there are a lot of sex scenes in the movie, so it’s kind of like ‘the love set,’ here.”

Joe and Ashley are even taking their love to more public places, like the Fresh Market, where they were spotted shopping together Oct. 20. The couple arrived around 4 p.m., and despite being bombarded by fans, a source tells us they couldn’t have been more friendly with the eager shoppers.
